President Andrew Johnson's Impeachment Trial, 1868

The galleries of the Senate Chamber were filled to capacity on March 5, 1868, as the Senate began its proceedings for the impeachment trial of President Andrew Johnson. Popular interest in the trial was so intense that the Senate, for the first time in its history, issued gallery passes, beginning a practice that continues to the present.
On May 16, the Senate voted on one article of impeachment, falling just one vote short of conviction and removal from office. Ten days later, the Senate voted on two more articles, with the same result. On May 26, the Senate acquitted the president and adjourned the Court of Impeachment. Johnson was not renominated for the presidency in 1868 but returned to the Senate in 1875, serving until his death on July 31 of that year.
